CONTAINER SEALING DEVICE Filed Sept. 17, 1950 INVENTOR. Isaac 7i6azforeff'arz ATTORNE Patented Mar. 21, 1933 I 1 ISAAC THEODORE KAHN, OF CLEVELAND HEIGHTS, OHIO CONTAINER SEALING DEVICE Application filed September 17, 1930. Serial No. 482,470.

My invention consists in a new type of scribed in detail. Brieflyit consists of emsealing member to be used in connection ploying a type of sealing member in which with a container, as an example of which I is punched one or more small holes so dehave selected a metal oil'barrel such as is signed as to accommodate an ordinary drive commonly used by oil refining companies screw and to be used in combination with 5 in the distribution of their products to the plug in the container, hereinafter styled wholesalers and retailers, together with the oil barrel or barrel, which also has one or means of attachment of such sealing memmore small holes so placed as to accommober. In such distribution of oil products date the small drive screw or screwswhich it is necessary to use such sealing members are first driven through the corresponding 60 for the purpose of identifying the products holes in the sealing member when it is of a particular company and to prevent placed over the upper surface of the barrel substitution of any other product for that plug. One or at the most several light taps of the company. with an ordinary hammer on the drive screw The structure of such sealing members is after the screw is placed-in the hole in the of light material, such as sheet metal, and upper surface of the sealing member will there is placed thereon the name of the comsuffice to drive the screw into the hole in pany whose products are in the container the upper surface of the barrel plug, firmly sealed. This seal should be destroyed and securing the sealing member to the plug and 0 will always be destroyed in the process of thus doing away with all need for bending removal, when drive screws are used, as I in the flanges of the sealing member around hereinafter point out. As at present am the plug, such as is now'necessary. One ployed in the oil industry, whose containscrew is enough as the hole or holes in the ers I have selected for the purpose of eX- barrel plug are preferably close to the plaining my invention, the sealing members center. a are manufactured in a variety of shapes and Such means of attaching the sealing memsizes made necessary by the correspondber has the additional advantage that it ing variety of shapes and sizes of the obviates the necessity of making a different plugs in said containers to which the shape of sealing member for every size and sealing members must be attached. This shape of container plug, for the reason thatvariety in style of the sealing members is in my plan of sealing it is unnecessary for largely due to the means of attaching them the flanges of the sealing member to fit, snugnow employed'because of the structure of ly around the sideseof the barrel plug as is the sealing member. As at present manunecessary under present means of attachfactured there is no device for attaching ment, for the drive screw through the hole' the sealing members other than that of or holes in the sealing member over plug bending the flanges or sides or lower edges serves to keep the seal firmly attached irreof the sides inwardly after the sealingmemspective of the proximity and general fit of her is placed over and around the plug the sealing member with the barrel plug.

hereinafter illustrated. To do this it is nec- Although the width or circumference of the essary to somehow bend the flanges of, the plug may vary, the distance it protrudes sealing member around the top of the barrel above the surface of the barrel is practically 'plug, or into undercuts made'for the puruniform in all cases,- and the lower edges of pose, with which some plugs are provided. the flanges of therrsealing member would To properly affix the sealing member in such therefore reach to the surface of the barrel fashion is by no means convenient and reimmediately around the barrel plug, irrequires considerable time. spective of the width or circumference of All this inconvenience in the manner of the plug. i 4 K0 attaching the sealing member is overcome Furthermore, under thecustomary means by my proposed invention hereinafter deat present employed of bending the flanges of the sealing member, it is exceedingly difficult to insert a screw driver, knife, or other implement between the flanges of the member and the side of the plug, in order to pry loose and lift the sealing member. Consequently, it is now often necessary to employ some such means as a can opener and to work from the upper surface of the sealing member in order to remove it. Under my arrangement, knife, screw driver, etc., may be readily inserted underthe flanges of the sealing member, and it pried off, the bending or destruction being highly desirable so that the seal cannotbe again used in any event. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

Theannexed drawing and the following description-set forthin detail certain mechanism embodying the invention, such disclosed means constituting,however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is a perspective View of the container; Fig. 2 is a plan view in cross section showing the upper portion of the oil barrel including the bung which is plugged and the plugsealed, the seal and plug embodying my invention; Fig. 3 is a planview of the uppersurface of the plug and the upper surface of the sealing member; Fig. 1 is the ordinary type of drive screw; and Fig.

5 is a cross'section embracing aportion of the top of the seal with the screw in place as when sealed.

In Fig. 2, there is shown a container, here represented as a metal o1l barrel 10 provided with a threaded opening 13 inthe side or top of the barrel, into which fits the threaded=plug 12 of'the barrel. The upperpor- 'tion 12Azofthe plug 12 protrudes when the plug isscrewed intothe barrel, which protruding portion of the plug extends horizontally beyond the threaded opening of the barrel and which is round, square, or hexagon in shape. The upper surface of this "part 12A'of the plug is flat, and has a square hollow center 19 for the insertion of a "wrench-'toremove the plug from the barrel opening. The wrench cannot be inserted without the destruction or mutilation of the sealing member.

In this upper surface of 12A of the plug,

aroun'd'the hollow center 19 are drilled the smallhole or holes 16, asshown inFig. 3, pleferably so spaced as to be at about the center of the upper surface; that is to say, between the outer edge of the upper surface of 12A and the hollow center 19, but closer to the edges of a hollow center 19, than the outer edges of 12A. This enables one drive screw to securely fasten the sealing member.

The hole or holes 16 are unthreaded for the reception of the drive screw 17, as shown in Fig. 1 and Fig. 3.

The seal let is constructed of a light weight sheet metal, and is of a size slightly larger than the protruding portion 12A of the plug, so that it will cover the plug and its flange 18-be approximately perpendicularly parallel to the sides of 12A, and extend to the surface of the barrel immediately surrounding the plug 12. As above pointed out, it is unnecessary to have the flange fit snugly around 12A in my invention, as the screw means of attachment is independent of the flange or fit of the sealing member. In the sealing member there is a small hole or holes 15, as shown in Fig. 3, arranged and located in a similar style as the hole or holes 16 in the upper surface of the plug, so that when the seal 1.4 is'placed over-the portion 12A of plug 12, the small hole or holes 15 coincide exactly with hole or holes 16. For fastening, the drive screw or screws 17 are then placed in holes 15 guarantee against future use.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means'statcd by any ofthe following claims or:the equivalent of such, be employed; j

I therefore particularly pointout and distinctly claim as my invention:

1. A metal container having a relatively small outlet, metallic closure-meanstherefor, a sheet-metal sealing member superand driven through into 16. As before men- C posable over and encompassing said closuremeans and of a shape to be destroyed on applying a removing-wrench tothe closure- -means, and securing means for said sealing member drivable therethrough into the metal beneath.

2. A metal containerhaving a relatively small outlet,-a metal plug for closing such outlet, a sheet-metalsealing member superposable over and encompassing said closuremeans and of a'shape to be destroyed'on applying a removing-wrench to the closuremeans, and securing means for said sealing member drivable *therethrough '-into the metal beneath. I

3..A metal. container having a relatively small outlet, a metal plug for closing such outlet, a sheet-metal sealing member superposable over and encompassing said closuremeans and of a shape to be destroyed on applying a removing-Wrench to the closuremeans, and securing means for said sealing member having steep spiral threads and being drivable through the sealing member into the metal beneath.

4. A metal container having a relatively small outlet, a metal plug therefor having a Wrench-hold, a sheet-metal sealing cap for covering and encompassing the Wrench-hold and plug and of a shape to be destroyed on applying a removing-Wrench to the plug, and securing means for said cap having steep spiral threads and being drivable through the cap into the plug.

Signed by me, this 15th day of September, 1930.
